Is it posible generate with scrypt "virtual" test transaction to real publick key(empty, without money any old publick key for ex) and get valid r,s,z for this transaction and this real publick key ?
Knowing the private key and creating an rsz is too easy.
You should be able to create rsz with only the public key.
I don't know if all of you can do it, but I can create an infinite number of public keys with just the public key.
You can test me.
